firebug: how to set watch when an <div id="abcd"> is changed by JS code?

I have a <div id="abcd"> which is changed by other c开发者_Go百科ode, I want to find out who is chaning that, can I set up a watch expression so that I can catch it in FireBug?

Thanks. Bin

Using Firebug 1.5 or 1.6, use the Inspect to select the element, then in the HTML panel, right click on the element and select eg break on attribute change or another one as you need.

See http://getfirebug.com/doc/breakpoints/demo.html

i don't know the exact wording in english, i use it in german. But if you click right on your div, there is a function called "explore element" (normally at the bottom of the context menu). Afterwords firebug displays that area where you can see all live changes...
